General description

Diacetin is a volatile acetylated glycerol used as a flavoring agent in e-cigarettes. It is also found in floral oil secreting plants, where it is reported to act as a signal for oil-collecting bees to locate these plants, thus playing a key role in pollination.

Application


  • Organ-specific volatiles from Sonoran desert Krameria flowers as potential signals for oil-collecting bees.: This study identifies specific volatile compounds, including Diacetin, emitted by Krameria flowers. These volatiles act as signals for oil-collecting bees, suggesting a specialized ecological interaction (Balbuena et al., 2024, Phytochemistry).

  • Techno-Economic Assessment and Sensitivity Analysis of Glycerol Valorization to Biofuel Additives via Esterification.: This paper examines the economic viability of producing biofuel additives, including Diacetin, through the esterification of glycerol, highlighting the process′s potential for cost-effective biofuel production (Pandit et al., 2023, Industrial & Engineering Chemistry Research).

The interaction between floral oil secreting plants and oil-collecting bees is one of the most specialized of all pollination mutualisms. Yet, the specific stimuli used by the bees to locate their host flowers have remained elusive. This study identifies diacetin
